F1 Cars "Aquaplaning"

"Aquaplaning" is in quotation marks because AIUI what happens is that they actually hydroplane on a film of water under the "plank".

So my suggestion for a way to reduce it is to raise the "reference pane" and hence floor to, say 75mm, and reduce the plank to 2x 50mm wide strakes bordering the sides of the area covered by the present plank.
